CRR 423/2002Ergonomics evaluation into the safety of
stepladders:

Phase 2: User profile and dynamic testing

Serves to summarise the project work undertaken as the second
phase of a study to evaluate the stability of stepladders,
particularly where intended for, or used in, the UK market. It
follows the phase 1 report which discusses the findings of a
literature search and standards review, and describes the test
methodologies used to examine the attitudes and expectations of
typical professional and domestic stepladder users as well as the
collection of dynamic data using an innovative platform. Later
sections interrogate this data in order to examine the manner in
which instability occurs in stepladder systems, relating it to both
the stepladder's structure and the user's behaviour. The
identified causes of instability are then reviewed in order to
determine effective safety intervention including proposed
improvements to the technical standards affecting stepladders,
increased levels of user training and better labelling and
warnings. A final section deals with possible avenues for the
dissemination of this vital information.
